[SOLVED] Building FPC AVR crosscompiler fails

[samtux]

Hi,
according to http://wiki.freepascal.org/AVR I'm trying to build FPC 3.0.2 from the sources in Slackware 14.2 but it fails with this message:

Any ideas how to make it build?

I also get that error when building a cross compiler using 3.0.2 source.  I would recommend using the trunk version of the compiler for AVR, quite a number of fixes have been added since 3.0.2. This would obviously need the 3.0.2 compiler to start the bootstrap build process.

@ccrause:
Thanks. You're right. Trunk version builds without errors.
